Running kernel does not match the kernel modules inside the nfsroot

[Romain Pelissier]

Hi!
In fact I have found the issue, and maybe it could be mentioned somewhere
in the documentation.
After any modification made in the tftp/pxe folder (/srv/tftp/fai)
(including adding or modifying a client's config) you need to restart the
tftp daemon in order to have the new parameters taking into account...
Seems like it caches the info somewhere even if it is not totally clear how
and where.. Anyway, it works now:)
thanks!
